Title: Improvements in or relating to aircraft
IPC: B64C27/28
Filed: 1928-02-15
Abstract: 311,719. Kirkby, J. S. Feb. 15, 1928. Machines supported by rotary propellers ; propelling; steering and balancing.-An aircraft is supported and propelled by rotary wings A each of which rotates about an axis which at the same time describes a conical path when constrained to do so by the pilot's control. Each wing comprises a series of radial flexible blades which open in a helical manner at that part of the wing which is rising. The wings A are mounted on shaft 2 knuckle jointed at B to vertical shafts 1 driven through Hooke's joints and rods E from pedals E'. The shafts 2 have sleeves connected to brackets on arms D provided with handles D<1> by which the shafts 2 are forced out of alignment with the shafts 1 to describe conical paths, the arms D' then remaining in constant movement. Fig. 5 shows a modification in which the wing A is mounted on a shaft rigid with two cross arms connected respectively to a driving shaft and to the inner ring of a ball race b pivoted in the same aircraft frame. A twist is applied to the frame to tilt, the ball race by a handle D<2>. In a further modification the aircraft frame is rigid but the driving shaft is tilted by cords connected to hand levers normally centred by springs. Fig. 8 shows a control lever D mounted in a roller H which is connected to a cord g passing over a pulley g' on the ball race. The cord g is connected at its other ends to a pivoted bar G<1> so that the pilot's weight restores the roller H to its normal position after displacement by transverse movement of the lever D. Fore and aft movement of the lever D tilts the lower shaft of the universal joint longitudinally. A mounting for the wing A equivalent to a knuckle joint is described but comprising a ball race of which the outer ring is connected to the control arm, and the inner ring, which carries the wing, is driven from the shaft E by a transverse pin. Fig. 12 shows two shafts 6, 7 connected by a universal joint which carries the wing A, the shaft 7 being connected to the control arm D which in this case does not move. as the wing oscillates, and the shaft 6 being driven.

Filed: 1965-02-04
Abstract: Thermoplastic yarns are joined together by holding, at one point, the yarns together with the ends extending in the same direction, at a spaced point applying heat to the ends to melt the ends, and at the first point withdrawing heat from the yarns so that the melting zone terminates thereat and joint is formed between the ends.  In one embodiment the yarn ends are held in a V-shaped wooden trough by two metallic jaws, one fixed and the other resiliently movable by a lever and spring arrangement. Adjacent the jaws an electric resistance heater is positioned.  A press button switch operates the heater.  In a second embodiment there is a hand tool in the shape of a pistol, the barrel of the pistol having a slot in which the yarn ends are inserted.  On retraction of a trigger, jaws in the barrel resiliently grip the yarn ends, and when the trigger is retracted beyond a latch position a switch in the circuit to a resistance heater adjacent the jaws and to a warning light is closed.  In operation the trigger is kept in the latch position for a few seconds after the heating to allow the joint to cool before a button is pressed to release the trigger and jaws.

Filed: 1917-04-17
Abstract: 114,495. Dearlove, J. A. L., Davidson, A., and Perryman, N. J. April 17, 1917. Receiving and repeating systems.-Block signals are broken up into their constituent elements by means of interrupting-relays which open the circuits of the re-transmitting-relays after a time determined by the time constant of the circuit of the interrupting-relay. In the arrangement shown in Fig. 1, the tongue 1 of the cable relay A is moved to the left by a, dot current and closes the circuit of the dot re-transmitting-relay 3 through the back contact of an interrupting- relay 8, the circuit of which is closed when the relay 3 attracts its armature. A condenser K and resistances R, R<2> are adjusted to retard the energization of the relay 8, so that the relay 3 is repeatedly energized to re-transmit dots at the proper speed. Relays 3<1>, 8<1> control the transmission of dashes in a similar way. A third interrupting-relay may be used to transmit spacing-impulses when it is desired to operate a perforator, the circuit of the third relay being closed when neither dots nor dashes are received. The Provisional Specification states that the interrupting-relays may be constructed like trembler bells.

Title: Improvements relating to pulse generating circuits
IPC: H03K3/45
Filed: 1967-02-06
Abstract: 1,124,873. Converting. INTERNATIONAL POLAROID CORP. 6 Feb., 1967 [7 Feb., 1966], No. 5549/67. Heading H2F. [Also in Division H3] Pulses (e.g. for the EHT supply of a cathoderay tube) are generated across the capacitance of a resonant circuit by alternately energizing the circuit in opposite series while its resonant frequency is high so as to ensure steep pulse edges, the pulses being sustained until the next edge as a result of the resonant frequency being low. When transistor 19<SP>1</SP> is momentarily rendered conductive the inductance of the circuit is short-circuited so that capacitor 25<SP>1</SP> charges resonantly through the leakage inductance of the transformer. When conduction ceases the full inductance of the transformer is effective so that resonant discharge takes place only slowly until transistor 21<SP>1</SP> is momentarily rendered conductive to initiate in a similar manner a negative output pulse. The pulse is raised in potential by the voltage applied at 31 so that the output at 30 alternates between 13 and 19 kV. Diodes 13<SP>1</SP> protect the transistors against reverse voltage and preferably the transistors conduct for somewhat less than half a cycle of the higher resonant frequency so that the pulses have a flatter top. In Fig. 4 (not shown) the D.C. is added to the output potential through a choke and is isolated by a capacitor from the windings. Separate primary windings may be provided (Fig. 4, not shown) or current may be fed in opposite directions through a single winding or autotransformers may be used. S.C.R's. or valves may replace the transistors shown.
